Problems solved by technology

Due to the low temperature of the working fluid supplied from the hydrogen bottle, it is easy to condense and produce liquid water after mixing with the high-temperature and high-humidity ejection fluid, which will easily cause the stack to be flooded, resulting in poor consistency and reduced life of the stack, especially in low temperature environments , the effect is more prominent
[0003] There are currently two heating methods for fuel cell hydrogen supply: one is to add a heating resistance wire to the pressure reducer or the medium-pressure hydrogen supply pipe, and use electric energy to heat the hydrogen supply gas. On the one hand, this heating method will

Abstract

The invention relates to a fuel cell and a hydrogen supply system heating structure thereof. The hydrogen supply system heating structure of the fuel cell comprises a galvanic pile metal end plate; the galvanic pile metal end plate is provided with a heat exchange flow channel; and the heat exchange flow channel is provided with an inlet and an outlet on the surface of the galvanic pile metal end plate. The heat exchange flow channel is arranged on the galvanic pile metal end plate, so that hydrogen supply gas flows through the heat exchange flow channel to exchange heat with the galvanic pile metal end plate, so that the hydrogen supply gas can be heated by utilizing the waste heat of a galvanic pile, and heating equipment such as a heating resistance wire does not need to be added, and therefore, the safety of hydrogen supply is ensured while the cost and the power consumption are reduced; the galvanic pile metal end plate is made of metal, is generally made of aluminum alloy and has good thermal conductivity. Compared with a cooling liquid pipeline heat exchange mode, the above heat exchange mode has higher heat exchange efficiency and avoids the increase of flow resistance of a cooling liquid pipeline; in conclusion, the heat exchange structure of the heating structure of the invention has the advantages of simplicity, easiness in implementation, good heat exchange effect, high heat exchange speed, and high reliability, and is particularly suitable for a fuel cell anode circulating system using an ejector.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell and a heating structure for a hydrogen supply system thereof. Background technique [0002] In the fuel cell system, the working fluid of the injector is the hydrogen decompressed from the high-pressure hydrogen bottle, and the injector fluid is the high-temperature and high-humidity mixed gas at the anode outlet of the stack. Due to the low temperature of the working fluid supplied from the hydrogen bottle, it is easy to condense and produce liquid water after mixing with the high-temperature and high-humidity ejection fluid, which will easily cause the stack to be flooded, resulting in poor consistency and reduced life of the stack, especially in low temperature environments , the impact is more pronounced. [0003] There are currently two heating methods for fuel cell hydrogen supply: one is to add a heating resistance wire to the pressure reducer or the medium...
